[Xymon] noconn in hosts.cfg not working properly? turns all 'conn''s purple

[Tom S]

So our XYMON host ISP seems to be having ICMP issues.
conn requests are randomly failing causing false alarms.
I added 'noconn' :
2.2.2.2. test.host # noconn  ssh ssh-tunnel -
However what happens is, it stops the test which is fine, but it holds
the 'red' status, or the last status it recorded.
After about 30 minutes it turns purple.

How can I get rid of the conn test altogether?

TIA!
